RESEARCH ON FIRE RESISTANCE OF PRESTRESSED CONCRETE

PCA HAS PROVIDED A NEW FIRE RESEARCH CENTER TO MEET THE PRESSING NEED FOR EXPERIMENTAL DATA ON THE FIRE RESISTANCE OF CONVENTIONALLY REINFORCED AND PRESTRESSED CONCRETE. THE RESEARCH IS DIRECTED TO: (1) FULL SCALE TESTS WITH LARGE FURNACES, AND (2) SMALL SCALE BASIC RESEARCH ON PROPERTIES OF CONCRETE AND STEEL AT HIGH TEMPERATURE. THE IMPORTANCE OF MASS AND COVER, AND PROPERTIES OF PRESTRESSING STEEL AT ELEVATED TEMPERATURES ARE DISCUSSED. THERE IS A NEED FOR BASIC RESEARCH TO ESTABLISH MEANS FOR PREDICTING FIRE ENDURANCE AND TO DEVELOP RELIABLE SMALL-SCALE MODELS. THE BRIEF DISCUSSION BY V. PASCHKIS INDICATES THE PROBLEMS ASSOCIATED WITH SMALL SCALE MODELS, AND THE USEFULNESS OF A COMPUTER TO INVESTIGATE THE RELATIVE IMPORTANCE OF THE MANY VARIABLES INFLUENCING THE FIRE ENDURANCES OF A MEMBER. /PCA/
